Transverse testicular ectopia usually occurs alongside other congenital conditions such as hypospadias (in which the opening of the urethra is not at the tip of the penis). C. acrosome. According to studies performed in mice, the final stages of sperm maturation appear to be regulated by a gene known as Katnal1, which is expressed by the Sertoli cells that support and nourish immature sperm within the walls of the seminiferous tubules (the site of spermatogenesis). A physical examination can help detect lumps, swelling, or other abnormalities on or around the testes. This has been Dysfunction of Katnal1 is suspected to underlie some instances of male infertility, and thus, the gene represents a potential target for the development of male infertility drugs as well as new forms of male contraception.
